The Cytochrome b (-245) protein complex is composed of cytochrome b alpha (CYBA) [1] and beta (CYBB) [2] chain.
NADPH oxidase 2 (Nox2), also known as cytochrome b(558) subunit beta or Cytochrome b-245 heavy chain, is a protein that in humans is encoded by the NOX2 gene. The protein is a superoxide generating enzyme which forms reactive oxygen species (ROS).
CYBA can refer to:
Beta-hexosaminidase subunit beta is an enzyme that in humans is encoded by the HEXB gene.
Lamina-associated polypeptide 2 (LAP2), isoforms beta/gamma is a protein that in humans is encoded by the TMPO gene. LAP2 is an inner nuclear membrane (INM) protein.
Integrin alpha-V is a protein that in humans is encoded by the ITGAV gene.
Integrin alpha-5 is a protein that in humans is encoded by the ITGA5 gene.
Platelet-derived growth factor subunit B is a protein that in humans is encoded by the PDGFB gene.
Cytochrome b-245 light chain is a protein that in humans is encoded by the CYBA gene involved in superoxide production and phagocytosis.
Eukaryotic translation initiation factor 2 subunit 1 (eIF2α) is a protein that in humans is encoded by the EIF2S1 gene.
A 2-oxoisovalerate dehydrogenase subunit alpha, mitochondrial is an enzyme that in humans is encoded by the BCKDHA gene.
Guanine nucleotide-binding protein G(t) subunit alpha-2 is a protein that in humans is encoded by the GNAT2 gene.
Alcohol dehydrogenase 1A is an enzyme that in humans is encoded by the ADH1A gene.
Guanine nucleotide-binding protein subunit beta-4 is a protein that in humans is encoded by the GNB4 gene.
25-hydroxycholesterol 7-alpha-hydroxylase also known as oxysterol and steroid 7-alpha-hydroxylase is an enzyme that in humans is encoded by the CYP7B1 gene. This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids.
Sodium/potassium-transporting ATPase subunit beta-3 is an enzyme that in humans is encoded by the ATP1B3 gene. ATP1B3 has also been designated as CD298.
Cytochrome c oxidase polypeptide 7A2, mitochondrial is an enzyme that in humans is encoded by the COX7A2 gene.
Cytochrome c oxidase polypeptide 7A1, mitochondrial is an enzyme that in humans is encoded by the COX7A1 gene.
CYP39A1 also known as oxysterol 7-α-hydroxylase 2 is a protein that in humans is encoded by the CYP39A1 gene.
CYP8B1 also known as sterol 12-alpha-hydroxylase is a protein which in humans is encoded by the CYP8B1 gene.
p22phox Protein, also known as the human neutrophil cytochrome b light chain (CYBA), is an essential component of the membrane-associated enzyme phagocyte NADPH-oxidase This enzyme uses NADH or NADPH as the electron donor for the one electron reduction of oxygen to produce superoxide anion, a reactive oxygen species (ROS), and a functionally important step for the antimicrobial activity of phagocytic cells. p22phox is also expressed in many other human cells such as endothelial and vascular smooth muscle cells, including those within the coronary arteries. Specific polymorphisms of the CYBA gene have been identified that are associated with a decreased risk of coronary artery disease (CAD).
